| Bus TRANSIT and TRANSIT TELEMETRIC Fuel Management Systems | |||
|
The Fully Automated Transit and Transit Telemetric System eliminates the need for operator input and speeds fueling, at the same time eliminating input errors. The Trak Fully Automated Transit Systems contain all the functional elements necessary to operate a transit fueling facility. The Fuel Sentry authorizes the fuel dispensers and oil reels, contains memory elements necessary to authorize all buses for fueling, stores a complete fueling record of all nightly transactions and communicates all fuel transaction records to the system’s Central Controller Computer. The Fully Automated Transit System eliminates the need for operator input and speeds fueling, at the same time eliminates input errors. Our WinCC Fuel Management Software manages all of the database functions of the system, including the storing of transaction, inventory, bus, vehicle, and personnel information. The buses each will have a SMARTag kit installed. This kit consists of a SMARTag and an ECM interface (DDEC, Cummings, International, etc.). The SMARTag is connected to the ECM interface of the bus and is mounted at the rear of the bus near the floor board. If the DDEC is not available the SMARTag is connected to the VSS signal of the transmission. When the bus approaches the fuel island the Trak SMARTag initiate the fueling identification, mileage transmission and authorizing process.
The SMARTag is a small on-board computer mounted on each bus and maintains information concerning that specific bus. The SMARTag automatically transmits odometer readings, bus ID, fuel/fluid type and limitk system ID and engine hours (if available). It contains an EEPROM circuit, that stores all the data in non-volatile memory -- which means it cannot be erased accidentally due to power failure. Our transit system allows vehicles not equipped with the SMARTag to fuel due to the Sentry's ability to accept manually entered data -- a PIN, or authorization to fuel via access with a Trak Chip Key or other compatible access methods. The SMARTag utilizes Extreme Short Range (ESR) - RF Identification. The SMARTag is potted and small allowing for great flexibility in placement.

Fueling Operation The driver pulls bus into the fueling lane where the system detects the Trak SMARTag, previously installed on the bus, that signals the fuel island terminal, the Trak Sentry, which turns on the dispenser. The Sentry communicates to the Data Storage Unit which identifies the Bus fueling. Once Bus ID is obtained, communication via radio begins. During the fueling process the bus information such as time/date for each trip, distance traveled, vehicle over speed, fuel pressure, vehicle ID, odometer reading, fuel type etc. are sent via the radio to the Data Storage Unit. All data is stored until polled. The entire transmission of data is done without the fueler having to do anything extra. |
